In other words our eyes can look but it is our brain that really sees.

Watching a super resolution display like an 8K TV, the brain actually has less work to do to.

Dr Lee says watching a lower resolution display with lots of artefacts and distortion requires a lot of effort from your brain to filter out the noise to make sense of the scene.

“That’s why you become fatigued or tired after watching poor pixelated display for a long time,” he said.

“With an 8K TV, your brain can spend more energy to get into the narrative and the story and enjoy the experience instead of filtering out the noise.”

Dr Lee says our brains need information to work out emotions from a human face on the screen but that becomes easier and faster to process when watching an 8K display.

“There was a claim that 2K (full high definition) was the appropriate level of resolution for retinal perception,” Dr Lee said.

“How the brain works is not limited by the resolution of the display.”

In fact Dr Lee says even going beyond 8K, our eyes might not be able to tell the difference but our brains have even more capacity than our eyes to detect and appreciate the added depth of the image and added visual information.

“There is no limit in the resolution that we should aim for,” he said.
